The blocks l() and 1l `are provided, respectively, with. terminals 15, i@ mounted on their opposing faces, and the terminals are connected by spring conductors or contact terminals l? carried by one of the blocks 10, ll the bleek ll, said spring means 17 being illustrated as tothe terminals lliand having yielding :tree ends deteehably engaging the terminals l5.

The terminals 15 are connected by suitable binding;r screws i8 to the stripped portions or ende of the line Wires 6, and the terminals 16 are eonneotedbythe conducting screws-i9 vand binding ydevices ,20, to wires 2l passing through the fixture Sto the lamp or other epplianee22, Fig. 5.

In the illustreted embodiment ofimy in vention Athe box 8 is shown as formed With laterally extending ears or Harige-.s 23 and with an outwardly extending lip or flange 24 around the opening of the box, this flange extending into the opening 2 of the Wall, and preferably terminating between the ends of the opening 2 and forming a facing' for the edge of such wall l. around the opening 2. As seen in Fig'. 'portions of the flange 2st are oxtensirnr.v of the long sides of the box and the-ears project 'from the Harige 24.

` The base 7 ot' the fixture' is preferablyl provided with a non-circular portion 25 rislso ing above the lace of the flange 9 engaging the Vall 1 und extending: intol the opening of the wall'l and having opposite substantially parallel sides engaging opposite sides of the opening 2, and when the parts are in their normal position, said portion 25 ahuts against the edge of the facing flange 24. Preferably the upper end of the rejection 25 isroduoed in size and is forme( with opposite substantially parallel ,sides enga-ging opposite sides of the opening in the outlet box.

The box 3 and base 7 of the fixture are clamped toward each other by any suitable means as screws 4Q6 passing tl'u'ough openings 27 in. the flange il of the base 7 through the opening of the wall 1 and into the` opening therein; of a conduit outlet box" iiange lapping the outer an. electrical appliance' including parts car-4 clamping action of the screws `26,
